. Thesev and other. objects areattained 'by-the means described herein and disclosed in the ace companying drawinga'in which: s v a Fig. 1 is'a perspective view illustrating a: rotat ing doortype of safe or chest embodying thejin-' vention. I Fig-2 is a front view of the Fig. l chest or safe, with the door thereof-disposed in the closed andlocked-position' a t Fig. 3 is a, cross-sectionalview. taken on line 3-3; of Fig. 2, showing part of the door infelevation;

' Fig. 4 is: a cross-sectionalview of a modification.

I Fig. 5 is a cross-sectional view of asecond modie fication. i 1 As is clearly illustrated in Figs. 1, .2 and '3 oi thedrawings, the rotating, door'type chest'ior safe may comprise any: suitable typeof-body 5 having a wall 6': providedwith-a: circular opening 7. 'The opening is closed or sealed bya rotatable door 8 which may be hingedly supportediby' the body as at'9, or otherwise supportedgforymovement relative to the body. :One methodofisupporting the door is illustrated in the drawings,

wherein 10 indicates av door: supporting member hingedly mounted upon the chest" at- 9, and. have ing provided therein an opening'12 in'which; the door supported for rotatory movement. The door may be rotated withinthe opening 12 by the use of any suitable means, such asa: handle ,13 secured thereto for moving" the door: lugsror abutments-15 to apositionbehind the cooperative lugs or abutments 16 onithe chest; wall6,'when the door is. closed. The circu1ar.rim' 17. of the door then cooperates with the circular jamb-18 on the safe or chest wall, for effecting a seal.

It will be noted, by reference toFig. [that certain of thestationary lugslfi are provided: with transverse slotszor' keepers19 for reception of one or more-sliding bolts-20 carried by the rotatable door; It should readily-beevident. "=that. these bolts whenenga ging the slots 19wi1l preclude the rotation of the door from the locked position. I The present invention is concerned with precluding actuation of one ormore locki'. 1g;bo1ts V zountila-nd unless the safe door is rotated to engage the-various lugs15 thereof with the correspondingzlugsltl of the safe body. To this end,

lock spindle or dial shaft 21, whichis mounted in. a bearingZZ' ofthe' bearing plate member 14;,

has-formed therein a, cut-out or notch 23, which may be in the nature of a flat, adapted to receive 3: sliding'la-tch bar 24 for the spindle. The spindle latch bar 24 may be in the form of a longitudinal v angular orround rod or: the like, having a substant-ially flat upper'end 25 and a lower endprovided with one or two inclines 26. 5 The lower end operate withaElatch; bar actuating means, which ted normally to coor more; inclined; faces 28' a with thetapered lower end 0 dapted, to cooperate f latch bar 24,-as indicated in Fig. 2,s o that rotational movement of the door relative to the notch, 27, will carrythe latch bar 24 from the notch and cause the lower endaof' the latch bar ,to ride upon the circular traoki-portionZQ-of the member; By thus effecting anelevating movement therupper end of said bar is cut-out or; notch 23 of the dial shaft or look of the latch bar 24, disposedwithin the spindle, ,whereby to preclude the possibility of rotating the; lock dialBO. until the door is finally rotatedtothe lockedaposition of Fig. 2, in which position the latch bar, 24 is lowered and removed from association withthe notch of spindle 21..

-From-the foregoingflit'will be understood that with 'theqelements.in the positions indicated in Figs. 2 .and'3, the dialv 30 and its shaft 21 may be rotated in any direction for the purpose of con- 'diti'oning, jthe tumblers of the door lock; however,

as soon as; the door is unloo 1,3. moved to, disengage; the lugs 15 and 16, the

latch bar12.4,wil15-be elevated ked, and the handle to engage the notch 2310f" the spindle and thereby preclude further rotational, movement; of the dial relative to the door; Upon closing thesa'fe, the-locking mechanism1may not beactuate'd by means of dial 30,

until the dooris rotated to the completely closed and-latched position, in. which position the latch bar 24; will fall; intothe seat ordepression 2'7 sov asto. clear the notch23 of the spindle, thereby permitting: free and unrestricted rotation of the looking meansr21-30; :A wayzorchannel 32 forme din ,thepart 14 Su ports the latch bar 24. Part 14 is secured to and movable with the door 8. The character 33 indicates a conventional lock in its cover plate.

In the modified construction illustrated in Fig, 4, parts corresponding to the various parts included in the Figs. 1, 2 and 3 structures, bear similar numerals with the letter A added to said numerals. The device of Fig. 4 is a chest or safe having a square or rectangular door 8A fitting the square or rectangular opening 18A.

In this Fig. 4 modification, the lock controlling spindle 21A is provided with the fiat or recess 23A which is adapted to receive the spindle latch member or bar 24A, this bar being slidable in a channel or way 32A formed in the body of the door. The lower end 26A of the spindle latch member is adapted normally to seat within a depression or flat 34 formed in the rotatable bolt throwing spindle 35, which spindle is rotatably mounted in a bearing 36 formed in the body of the door. The bolt throwing spindle may be provided with any suitable type of handle 37 which. is accessible from the exterior of the safe or chest. When the bolt A and the associated actuating parts 3537 are in the position shown, for maintaining the door in thelocked condition, the lower end 26A of the latch bar 24A is resting within the flat or recess 34 of spindle 35. The upper end 25A of the latch bar then is lowered or retracted relative to the lock controlling spindle 21A, so that said spindle may be freely rotated for actuating the lock mechanism 33A by means of the dial or handle member 30A. As is well known amongst persons skilled in the art to which this invention relates, the member 30A is adapted to be rotated forwardly and back various degrees of rotation, for the purpose of throwing lock tumblers, until the lock tumblers finally are positioned so that the handle 37 may be moved for retracting the bolt 15A. The spindles 35 and 21A are so co-ordinated that the flat or recess 23A of spindle 21A will be in position to receive the end 25A of the spindle latch bar 24A when the element 3537 is rotated so as to elevate the member 24A due to the cam action between the parts 34 and 26A. When so elevated, the terminal end 25A of member 24A'will enter or abut the fiat 23A of the lock controlling spindle, so as to preclude rotation of the lock controlling spindle 21A whenever the bolt-throwing spindle 35 is rotated to maintain the spindle latch member 24A in the elevated or latching position. Thus, it will be readily evident that rotational movement of spindle 21A is precluded whenever the spindle 35 is rotated to the bolt retracting position.

In the Fig. 5 modification, the parts corresponding to similar parts shown in Figs. 1, 2 and 3 are indicated by the same numerals, followed by the letter B. The Fig. 5 structure illustrates the type of safe or chest wherein the door 83 is not rotatable, but may be swung on a hinge 9B which is fixedly secured by welding or otherwise, relative to the body of the door 8B. In this modification, the spindle latch member or bar 24B is spring urged against the door jamb 18B preferably by means of a spiral compression spring 38 which has one end abutting a shoulder 39 on the member 24B, the other end of the spring being adapted to abut a shoulder 40 of an enlarged bore 41 which receives the spindle latch bar. The bore 41 preferably is concentric with the bore 323. Outwardmovement of the spindle latch bar is limited in any suitable manner, such as by means of a stud or the like 42 carried by the door and extended into aslot or way 43 provided in the material of the spindle latch bar.

The lock controlling spindle 21B has formed therein a transverse bore 44 in which is reciprocably mounted a short plunger or looking piece 45 which is always urged outwardly of the spindle by any suitable means such as a coil spring 46. As will be understood the plunger or extendible member 45 normally is confined withinthe limits of the spindle 21B, by the wall of spindle bore 22B, and. by the inner end 25B of the spindle latch bar. As is evident from the disclosure of Fig. 5, an outward swinging of the door 8B after retraction of the bolts 15B will result in a downward or outward movement of member 24B, due to the action of spring 38, under which circumstances the member 45 will be projected downwardly, by spring 46, into the bore 32B-whereby to lock or latch the spindle 21B against rotational movement relative to the door. It is to be understood that the member 45 will assume a position in alignment withthe spindle latch bar 253 and its bore 323, only after. the lock controlling spindle 213 has been manipulated to unlock the lock 33B and retract the bolts 15B. Thus, when the member 45 is inengagement with the bore 323, the bolts will be retracted so that the door may be swung open about its hinge means 9B. When the latch bar 24B is abutted by the door jamb 183 as shown, there can be no latching of the lock controlling spindle 21B, for in this position of the latch bar 243 no part of the bore 32B is open for reception of the spring urged stud or plunger 45. It will thus be clearly understood that whenever the door of the Fig. 5 structure is open, the plunger 45 will be partly extended into the bore 323 so that the lock controlling spindle 21B and .its handle means 30B will be latched against rotational movement by the operator. As is evident, the way or slot 43 will permit only a partial entry ofmember 45 into the bore 32B. The door 83 may be either circular or angular, for the shape of the door does not affect the operation of the mechanism contained in the door. The same is true of the Fig. 4 modification. The mechanism for advancing and retracting the bolt is of the well known type wherein manipulation of the lock controlling spindle to throw the lock tumblers is followed by a final movement of the spindle that results in retracting the door bolt.

It is to be understood that various modifications and changes in the'structural details of the device. may be made, within the scope of the appended claims, Without'departing from the spirit of the invention.
